"Did a great job on the insulation however they left a hole in the ceiling when they dropped something on the attic floor. Not a big deal but they need to be careful. Overall, amazing work they do all kinds of insulation and they also install radiant barriers on roof joists. They are reasonably priced and the crew is super friendly, pleasure to work with."

"Contacted Master Attic via Angi and Alex, the technician came to evaluate our attic and crawl space (2 separate spaces in our house). We heard critter noises and our upstairs was hot in the summer. The insulation was original to the ~30 year old house, so we know it's about time to get it done. Alex checked both spaces and showed us photos of problem areas. We have an estimate and Alex explained the details of the work involved. The team came within the week (we lucked out to take the spot of a cancellation), and everything was done as expected. There was a lot of work to remove old insulations, vacuum all debris, sanitize the space, seal all air gaps, install baffles, rodent proof, and install new insulation. The work was completed in around 6 hours, the spaces are now clean and tidy - quite unbelievable given how they were before. We went for the heavier insulation which is reflected in the project cost."

Drywall Insulation FAQs, answered by experts

Knowing what causes drywall damage can help stop it before it starts. Here are some of the most common causes of drywall damage: 

  • Water damage from roof leaks or leaky pipes. 

  • Small holes caused by doorknobs, minor accidents, and rodent infestations. 

  • Wall dents stemming from moving furniture and minor accidents. 

  • Wall cracks that form from a settling foundation or seismic activity. 

  • Nail pops from nails and screws in the walls. 

  • Large holes that are caused by accidents with heavy objects, children and pets, or sporting equipment.

Drywall can be toxic to the environment and to humans in some cases. As drywall breaks down in a landfill and comes in contact with other organic chemicals, it can create hydrogen sulfide gas or leach into the groundwater. Additionally, the CDC recommends methods for controlling the inhalation of drywall dust when handled. While the common ingredients of drywall—gypsum, silica, and mica—are naturally occurring, they can cause irritation in some humans.

You should always hang drywall from the top down. Starting at the top makes it easier to create a straight, tight line between the ceiling and the wall. Any gaps that occur will be at the bottom, where they are easier to manage. You can either cut the bottom piece of drywall to fit the remaining space or cover the gap with baseboard trim. Additionally, starting at the top is physically easier, as you won't have to fit the top sheet into a tight space between the lower sheet and the ceiling, or try to balance the upper sheets on the lower ones while securing them.

Plaster ceilings can sag for several reasons. In some cases, the plaster and other building materials shift and come apart over time, which is why you’ll commonly find drooping plaster ceilings in older homes. Improper installation, foot traffic, and water damage—often from a leaky roof or a broken pipe—can also cause plaster ceilings to sag.

In many cases, installing new drywall will boost your home value. Replacing old, damaged, cracked, or wavy drywall is a great way to improve the look and feel of your home, as new drywall installed by a professional shouldn’t have any imperfections. Additionally, removing old drywall means you’ll have open walls, so you can install new insulation and address exposed issues with plumbing and electrical systems running behind the walls. All of these fixes will also add to your home’s value.
